A radioactive tracer is a radioactive element or compound added to material to monitor the material's distribution as it progresses through a system. The use of a radioactive tracer is called radiolabeling, which is one form of isotopic labeling.

Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.
Radioactive dating enables geologists to record the history of the earth and its events, such as the dinosaur era, within what they call the geologic time scale. Radioactive dating uses the ratios
Research has even identified precisely where radioisotope dating went wrong. See the articles below for more information on the pitfalls of these dating methods. Fluctuations Show Radioisotope Decay Is Unreliable. Radioactive isotopes are commonly portrayed as providing rock-solid evidence that the earth is billions of years old.
Carbon Dating - The Premise Carbon dating is a dating technique predicated upon three things: The rate at which the unstable radioactive C isotope decays into the stable non-radioactive N isotope, The ratio of C to C found in a given specimen, And the ratio C to C found in the atmosphere at the time of the specimen's death.
Radioactive decay of a radioactive substance or material can be measured by the half-life, which is the time it takes for the radioactive material to decay to half of its original amount.
What Is Half-Life? Half-life is defined as the time it takes for one-half of a radioactive element to decay into a daughter isotope. As radioactive isotopes of elements decay, they lose their radioactivity and become a brand new element known as a daughter isotope.
Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods. Relative dating uses observation of location within rock layers, while radiometric dating uses data from the decay of radioactive substances within an object. Relative

Radiometric dating--the process of determining the age of rocks from the decay of their radioactive elements--has been in widespread use for over half a century. There are over forty such techniques, each using a different radioactive element or a different way of measuring them.
Radioactive decay (also known as nuclear decay, radioactivity or nuclear radiation) is the process by which an unstable atomic nucleus loses energy (in terms of mass in its rest frame) by emitting radiation, such as an alpha particle, beta particle with neutrino or only a neutrino in the case of electron capture, or a gamma ray or electron in
